To all 'whom t may concer/n.' Y

Be it known that I, ARGYLE CAMPBELL a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Divertible Ballast- Cars, of which the following is a full, clear, concise, and exact description, reference be ing had to the accompanying drawings, forming a part of this specification.

This inventionrelates to improvements in divertible ballast cars.

Objects of the invention are to'provide a hopper car more particularly adapted for use as a ballast car and wherein the loadcarrying capacity of the car is increased as compared with former constructions; the amount of material employed is decreased as also the cost of fabrication; and wherein the dumping of all the ballast between the rails, when the car is employed for center dumping, is insured, the present invention being in the nature 0f an improvement upon my prior Patent No. 1,174,677 of March 7, 1916.

In the drawing forming a part of this specification, Figure 1` is a transverse, sec- A tional view of a car embodying my improvef ments, the section of the left hand portion of the car being taken through the center of a hopper and the section of the right hand portion of the car being taken through the l end of one of the hoppers. Fig. 2 is a part horizontal section, part top plan of a portion of the car at one end of the hopper section of the car and showing more particularly the arrangement of the door operating mechanism. Figs. 3 and 3a represent a broken sectional view at the ends of the hopper section t0 more clearly illustrate the operating mechanism for the Center dumping doors. Fig. 4 is a side elevational view of a portion of the car at one end of the hopper section. And@ Fig. 5 is a partial side elevational view of a portion of the car opposite one of the diaphragrns between two of the hoppers.

center sill 10 which is preferably in the form of an I-beam to thereby obtain a center sill of minimum width consistent with the necessary strength and the purpose of which will more clearly appear hereinafter. In addition to the center sill 10, the car is provided with side walls 11-11, side stakes 12-12 and pressed channelshaped diaphragm members 13.

Each of the hoppers hasa downwardly and inwardly inclined hopper bottom sheet 14; a downwardly and outwardly inclined hopper bottom `sheet 15, the latter being secured at their upper edges to the web of the I-beam 10 and beneath the upper ianges thereof, as indicated at 16; end hopper sheets 17, the latter being secured near the middle of the channel diaphragme 13 so that the latter are employed to form portions of the hoppers and thus save material; a side dumping hopper door 18 hinged along its upper edge, as indicated at 19, to the under side of the hopper sheet 14; anda center dumping hopper ldoor 20 hinged along its upper edge, as indicated at 21, to the lower under side ofthe hopper sheet 15. Each set of hopper doors 18 and 2O is provided with meeting flanges 22 and 23 at the bottom edges of the doors and beneath the meeting edges of the doors is disposed a longitudinally extending divertingpartition 24 which is preferably in the form of an angle, the angle Q4 being carried by suitable brackets 25 attached to the end hopper diaphragm members 17. The hopper bottom sheets 14 and 15 are suitably braced at their bottom edges'as by angles 26S-26, the bottom edges of the `hopper doors by Z-bars E27-27 and the upper edges of the hopper doors by angles 28-28- As clearly appears from Fig. 1, the meeting edges of the doors of the hoppers are located in a vertical plane 'are vdisposed entirely below the diaphragm members so that it is unnecessary to slot or cut the diaphragm members, thus saving considerable labor in the manufacture of the car. From each of the shafts 30 extend a plurality of connections for the hopper. doors, there being one moreset of con nections than there are number of center dumping doors on each side of the car, that isthere will be connections from the shaft 30 at each end of the hopper section and connections between each pair of center dumping doors. Each of these connections includes a hook-shaped link 32 pivotally connected Vto the hopper door, as indicated at 33; a short link 34;. an additional link 35, the link35 being `pivotally connected,las indicated at 36, to an arm 37 carried by a drum rigidly secured. to the shat't 30.A The connections above described are of a well known formandare. so arranged that when the doors are in closed position, tendency to rotate the'shaft 30 in an unwinding direction iseliminated.V Atene end of the hopper sect-ion, as shown most clearly in Figs.

' 3 and 3a, the shafts 30-30 are provided with worm v gears mounted in housings 38, the worm gears meshing with worms mounted in housings 39, the Vworms being carried by a transverse operating shaft 40 which is eX* tended to one side of the car, as shown most clearly in Figs. 3 and4. At its end, the shaft 40 is provided with the usual ratchet wheel 42, squared end 43 by` which it can be turned, and coperating with the ratchet wheel 42 is a pawl 44 and aI locking dog 45. As will be apparent, the worm and worm gear connection between the shaft 40 and shafts 30--30 will automatically lock the shafts 30 in any desired position so that the degree of opening of the center dumping doors 20can be adjusted and maintained as desired, both sets of doors 20 being operated simultaneouslyV and uniformly. Each set or' side dumping doors 18 is operated independently and for that purpose l providethe following mechanism: Secured to the lower flanges of the center sill l0 at theends ofthe hopper section and intermediate each pair of hoppers, are depending Vhanger brackets 46 `each. otvwhich is provided with a pair of` bearings 47'--47.

Mounted in said bearings are two longitudinally extending operating shafts 48-48, one for one setof s ide,dumpingdoorsand the other for the opposite -set'ot side dumping doors.' From eachshat 48 to the set of side dllmpligddoors .18 on the same sideof the carextend. sets of link connectionssimilar to the ,link connections previously described in connection with4 the center dumping doors, the `elongated hook-shapedlink members 49-49, of whichv are :most clearly designated. in Fig. l. In order to economize the material required for the hanger brackets 46, and also to economize space, the link connections `to the side dumpdoors onone-side of the car.arc located` on one side of the bracket and the link connections to the side damp doors-to the opposite side of thecar are located on the opposite side of said bracket,fas clearly appears fromFigs: 1 and 2. At one end of the hopper sections, one of the shafts 48 is extended and mounted in a bearing 50, as indicated-inV Fig. V2 andy on the extended section is provided with apair ot' sheave wheels 5l'51*over which run chains 52-52, the chains 52 beingcarried at the side of the car bysheave wheelsl i 53-53 mounted on a lstudshaft 54 extended parallel to the side of the car,y Said stud shaft 54, as appearsmost clearlyfrom Figs;` l and 3, is provided at-its end with ratchet wheel 55 having the -pawl 56 coperable therewith.V The stud-shat't54 is provided with suitable donbleq-j acting-1,paw-l-Iv and ratchet mechanism, asindicated contentionally at 57 in Fig-,1, and adapted tobe oper-l` nected Vto extension brackets 59 carried byv p the hopper doors 18 and where the links 49 are located between a-pairof hoppers, they are ,pivotally connected to cross brackets 6G which are riveted to each adjacentpair of doors'l8 so that each setof doors lSoneach side of thecar will be operated .as a unitl By employing av single narrow center sill, as illustrated in thedrawings, the hopperI bottom sheetsV 15-15 can be brought very close together thus lowering the position occupied by the downwardly` and outwardly inclined hopper sheets and adding to the capacity of the hoppers.` Furthermore,"the location speciiedof therhopper sheets=15 serve to bringthe meeting edges ofthesets of. hopper doors 18 and 20 nearer the center line of thecar to thereby insure dumping oi the load well .withinthe rails.

rangement of 1 centery sill/construction also permits of the operatingfshafts48+48being brought closely together toijeconomize space and permit ample openingmovemento't the.

doors 20-20 and furthermore, theflocation,

of the `shafts 48 below-the center. `sillY eliminates the necessity-.of cuttingv orrecessing anybfthe diaphraginxmembers. Theiem-f ployment ,ofthe single center sillandfpor` tions of the. diaphragm Vmembersl3 as parts` of the ends of .thehoppers materially decreases the amount of material necessary in the car while at the same time providing the increased capacity, as above described.l

Although I have herein shown and described what I now consider the preferred manner of carrying out my invention, the same is merely illustrative, and I contemplate all changes and modifications that come within the scope of the claims appended hereto.
